What Is Fetal Echocardiography
Fetal echocardiography is a test similar to an ultrasound. This exam allows your doctor to better see the structure and function of your unborn child's heart. It's typically done in the second trimester, between weeks 18 to 24. The exam uses sound waves that "echo" off the structures of the fetus's heart.
It's not necessary for all women to have a fetal echocardiogram during pregnancy. The prenatal ultrasound tests that are done routinely prior to birth can give information about whether the fetal heart has developed all four chambers. Most unborn babies do not require any further testing.
A fetal echocardiogram is done in a darkened room, while you are lying down. It is similar to a routine ultrasound during pregnancy. Gel put on your belly helps sounds waves travel from the echocardiogram wand (called the transducer) to the baby's heart and back again.
This test is not painful and causes no harm to the baby. The test takes an average of 45-120 minutes depending on the complexity of the baby's heart. Endovaginal ultrasound: this ultrasound is typically used early in pregnancy.
